HNGE-RECESS GAUGE.

Application filed June 26,

To all whom t may cof/wem.'

Be it known that I, RAY L. CARTER, a citizen of the United States, residing at Syracuse, in the county et @nondaga and State of New York, have invented certain new and useful lmprovements in Hinge- Recess Gauges, 0i' which the following is a specification.`

rihis invention relates to gauges, designed for use by carpenters, for accurately locating and gaging and cutting the recesses or sockets in which the leaves of door-butts or hinges may be disposed.

The primary object of this invention is to provide a hinge recess gauge or templet, which may be readily applied to door frames, wherein the jambs and lintels are correspondingly rabbeted for providing solid, instead of removable, abutments for stopping and supporting the doors when they are closed. A further object is to provide a templet of the class, which is especially adapted for supporting and guiding a power-driven routing machine while the recesses are being formed. And a further object is to provide a recess gauge composed of similar sections or units, one for each hinge, wherein each section is equipped with adjustable means for laying out hinge recesses of dierent lengths, breadths and depths; the said sections being arranged for mounting upon a common guide-rod, which is normally positioned beyond and clear of the door and iframe during the gaging and routing operations.

A particular obj ect is to improve and slmplify the devices shown and described in my pending application, Serial No. 670,026, iiled @ctober 22, 1923.

I attain these objects by the means set forth in the detailed description which follows, and as illustrated by the accompanying drawings, in which- Figure l is a broken vertical section of a door-frame, to which my sectional recess gauge'is applied. Fig. 2 is a horizontal section, taken on line 2 2 of Fig. l, and a toppla-n view of the gauge. Fig. 3 is a broken edge view of a door; showing the lowermost unit of the gauge of Fig. 1 inverted Y and applied to the top portion of the door.

.Figa 4 is a broken front side elevation of the door, and an edge view of the gauge ol' Fig. 3. Fig. 5 is a rear face view of one of the sections of the gauge. Fig. 6 is a broken rear face view of the door, with i924. Serial No. 722,548.A

the gauge attached; showing a motor-driven router in the act of cutting the top-hinge recess. Fig. 7 is a detached view of the tubular clamp. And Fig. 8 is respectively a front face and an edge view of one of the slotted plates by which the height of the recess is gaged.

ln the drawings, 2 represents one of the jambs of a door-frame, 2 the lintel, and 2a the corresponding rabbeted portions of the jamb and linlet which receive the lateral and top margins of the door 3.

My sectional hinge recess gauge consists of two or more similar normally open frames or members, as A and B, each of which is provided with one plain straight lateral edge a', which parallel the solid abutment 2b of the jamb, as well as the corresponding iace 3 of the door 3, as shown in Figs. l, 2 and 3. The opposite edge of the frame (A or B) is provided with laterally projecting spaced integral guide-lugs li, having alining perforations to receive a common guide-rod 5, upon which the several trames or members may be adjustably mounted. The frames A--B are held in place on the rod 5 by means of similar novel clamping devices, which consist of tubes 6, whose length equals the space between the lugs 4, and which slidably receive the rod 5; the top ends of said tubes being split, as at 6. The split ends of the tubes 6 telescope perforated blocks, as 6a, the latter being provided with transverse threaded holes into which is screwed set-screw 6", whose inner ends engage one jaw of the tubes and compress said jaw against the rod 5, for rictionally holding the gauge parts in the adjusted positions. The lugs a are also provided with transverse threaded holes that receive adjusting screws 4f, which pass beneath the rod 5 and their free ends overlie the bottom tace of the frame, as shown in Figs. l, 2, 3 and 5. rlhe vscrews 4L are employed for adjusting the frames A-B, when the latter are applied to the jamb 2, as shown in Fig. l, wherein the said screws are in engagement with the outer edge ot the jamb, for gaging the breadth of the recesses (L -b. The rabbeted portions 2a are usually about two inches in breadth, for accommodating doors that are two inches thick. lVhen doors of less thickness are to be hung in the rabbeted jambs, the frames A and B are adjustably set, by means of the screws ll (See best seen in` Fig. 1'.

Fig. 1), the required distance from the abutment 2b, and the vacant space, indicated at 2c in Fig. 1, is usually fitted with a liner or strip 2d, for closing the said gap. W'hen heavier doors, whose thickness equals the rabbets 2a are to be hung, all the frames of the recess gauge are adjusted inwardly, by reversing the screws 4 until the plain edges" of the-.frames substantially abut against thek ledge 2b, as shown by dotted lines in Fig'. 1.

,The frames A-TB preferablyv comprise similar parallel side-.railsand 7', which are spaced to .a slightly greater extent than the breadth of the leaves of thelargest hinges in.` common .use,.by means .of similar relatively th-inl webs 7, which are spaced to provide relatively long openings 7b (see Fig. 5) .that register with the hinge recesses, and through which .a routing orv other recessing tool 12imay. be inserted, as shown in Figs.

Y5 tand .6. At theopposite ends of the rails 'similar guide-.plates 8, which are slidablymountedl on the top faces of the webs. 7, between the rails 7-7, as shown in Figs. 1,; 2and 3'; `the said plates being adjustablyheldfin place by screws 8', which pass through slots 8a of the plates andare threadedintlthesaid webs. Theouter ends of the plates 8' are formed with similar heads 8b,y.which play in longitudinal slots of the webs," as at 7e, and one head of each pair ofY plates is boredv out (seel Figs. 1, 3, 5 and 8)` to receive a short rod 9, which constitutes one member' of an adjustable limitgauge, the other member of which comprises a .tube 9', whichisslidable on the rod, for varying the distance between the top hingeA and the bottom surfaceof the lintel 2, as For this purpose, the rods 9 are provided with single perforations, as 9, to receive cotter Vor other pins 9b, which may be inserted through either one' of several'perforations 9c formed in the tubev 9 `(see Fig. 4). The free end of each tube 9 is fitted witha laterally projecting arm 9d, the said arm being relatively thin for gaging the usual narrow clearance between the top edge of the door 3 a-ndithe lintel 2', as shown by dotted lines in Figs. 1 and 3. The lowermost plate 8 of the frame B is also provided with similarlimit-gauge parts (see Figf1), which depend idly, while the templet is being employed for locating and forming the recesses of the jamb 9 llVhen the operator is ready to cut the recesses in the do'or 3, he releases the templet from the jamb and inverts it, for positioning the frame B near the top end of the door, as shown in. Fivs. 3 and 4. This inversion of the tempet disposes the guide-rod 5 at the left side of the door, thus reversing the order of the recesses 3 of the door, as compared with the recesses a-b of the jamb. The frame B ispreferably held with its plain edge rail 7) flush with ,the outer face of the door, by a pair of stops 10, which are piv-` oted to the rail 7 by screws 10, and which may be swung downwardl f for overlapping the door, asbest seenin ig. 4;l The Sto 10 are swung into alinenient with the rails 7 when the templet is applied to the jamb (seev F ig. 1), and being preferably relatively thin serve to slightly space the inner face of the door from the abutment il, or from the liner 2, as shown in Fig. l, for preventing chaling of the door. Upon reversing the templet for mortising the door 3,.the arm 9c 0f frame B is hooked over the top end of the door, as shown in Figs. 3, 4 and 6. By this provision and arrangement, the several recesses of the door will be suitably located, for providing the usual clearance at the top of the door, when the latter is finally hung.

The routing tool 12 is driven by the shaft 12 Vof a motor 13, which is enclosed in a threaded casing 13', the latter being screwed into a hollow support 14, for adjusting the tool 12 relatively to the fiume B, for regulating theV depth of the recess The bottom of the holder 13 is preferably flat and smooth, and is adapted to slide over the top faces of the rails 7-7 during'the rout-ing work. The tool 1:2 extends belou` a cylindrical guide 13b, which is attached to the motor shell 13. This guide bears against the inner faces of the rails 7 7', and also against the facing ends of the guide-plates 8, as shown by dotted lines in Fig. 1. By this arrange-ment of the pairs, the recesses are smaller than the clear openings in the frames A*B, ras shown by dotted lines in Figs. 1 and 3.

For doors equipped with more thantwo hinges, plain frames similar to those shown in the drawings, but without the limit gauges 9, may be adjustably mounted on the rod 5 between the frames A and B, for g Y- ing the additional recesses.

From the foregoing, it will be understood that the recess gauge of my pending application, is not` adapted( for gaging hinge recesses of rabbeted door-jambe, as herein shownl and described. The present invention is designed to perform the same functions as the former device, but in a sinu'der manner, with fewer parts, and with greater convenience, accuracy and economy.

Obviously, with a few slight changes in the construction and arrangement of some of the parts, thepresent invention may be adapted for gaging many different kinds of work, and I therefore do not limit its use to hinge recesses.
